Laravel 13 now supports MariaDB Vector natively
If your Laravel application runs on MariaDB, you can add semantic search to it without a second database, an external vector service or an extra package. Since Laravel 13.28, vector columns, vector indexes and similarity queries work on MariaDB out of the box. A large part of that work came from community contributors, including Mohamed Touhami Rhaima.
Until this summer, Laravel’s built-in vector search was a PostgreSQL feature: it assumed pgvector. Laravel’s AI SDK documentation now reads: “Vector queries are currently supported on […]

From a Chocolate Wrapper to Concurrent InnoDB Page Splits
This work started from a conversation with Monty Widenius at Meet Magento Czech in August. We discussed possible ways to improve the scalability of the InnoDB B+Tree, especially its insert path and page splits.
Monty explained several ideas about reducing synchronization during structural changes and allowing independent parts of the tree to make progress concurrently. We did not have a whiteboard, so we made the first design sketch on the back of a dark chocolate wrapper.
The sketch contained a […]

From a Production Problem to MariaDB: Headout’s Open-Source Contribution Journey
A production bottleneck at Headout led to a new MariaDB Server improvement. This is the story of how engineers, maintainers and AI-assisted development turned a real-world problem into an upstream open-source contribution.

MariaDB 13.1 Feature in Focus: BLOB, TEXT, JSON and GEOMETRY Support in the HEAP Engine
Some contributions improve MariaDB Server by adding new capabilities.
Some go further: they start from a concrete production problem with an existing feature, not a bug, but a design limitation, solve it upstream, and leave the whole ecosystem better off.
This is one of those contributions.
The platform team at Headout, a global platform that helps travelers discover and book curated real-life experiences, encountered a few inefficiencies in MariaDB Server around temporary tables and the HEAP engine. Instead of treating […]

MariaDB 13.1 Feature in Focus: DENY / Negative Grants
MariaDB 13.1 Preview is full of nice things.
Some are immediately visible to developers, like the new JSON operators. Some are very useful to DBAs, such as configuration validation. And some are about making security and access control easier to manage.
Today, let’s look at one of those: DENY, also known as negative grants.
Yes, negative grants.
It sounds a bit strange the first time you hear it, but the idea is very simple:
Sometimes it is easier to say […]

MariaDB 13.1 Preview: This One Is Full of Community Goodies!
We just announced the availability of a preview of the MariaDB 13.1 series.
MariaDB 13.1 is a rolling release preview, and, as usual, this is the right moment to test what is coming, give feedback, and help us polish the next MariaDB Server release.
But this time, there is something really interesting.
And by “interesting”, I mean: wow!
MariaDB 13.1 Preview includes 32 MDEVs with new features and improvements. To put that in perspective:
That is almost twice MariaDB 13.0, […]

Simple tool to build MariaDB commits for performance-change analysis
Tracking down changes in database performance is one of the hardest parts of engineering, especially when the change is buried somewhere in a long commit history.
To make this work easier and more repeatable, I put together a small but important tool:
MariaDBCommitBuilder.sh
This script does one thing well:
Given a commit hash, it checks out that commit, builds it cleanly, and packages it in a deterministic way so the Test Automation Framework (TAF) can run consistent performance tests.
Why […]
